| description | The invention discloses a high-speed railway soft rock deep cutting roadbed long-term deformation blocking structure which comprises flexible blocking structures arranged on the two sides of a roadbed at intervals in the longitudinal direction of a line, and the flexible blocking structures are formed by filling deep grooves excavated in foundation rock mass with flexible composite materials. The flexible composite material is formed by mixing polystyrene (EPS) foam particles, waste tire rubber particles and polyurethane resin (PU), the polyurethane resin (PU) is a cementing material, the polystyrene (EPS) foam particles and the waste tire rubber particles can be effectively cemented into a composite material with good compression resistance and tensile strength, and the composite material is also a waterproof material. Groundwater permeation can be prevented, a waterproof curtain is formed, and polystyrene (EPS) foam particles serve as coarse aggregate of the flexible composite material.
